Are people trying to say that compression happens before the assets are allocated?

With the way color compression works on Tonga (delta color compression), you'd still need the whole asset in VRAM... The color compression only helps bandwidth, you still need the capacity.

So, does Fiji have some way around the capacity problem?
Clearly Tonga's loss-less compression is not it.

(Assuming the first Fiji release has only 4GB VRAM)

For those in North America (Inno3D isn't sold here), you can get a hybrid cooler from EVGA, but it has a blower fan on the card instead of an axial fan...

I have no idea what AMD has up their sleeve...

So based on an unknown AMD compression that you know nothing about, up to and including it's existence, and unknown DX12 you have surmised that 4GB is adequate.

Talk about a logic fail. You'll have to do better than that to convince anyone who isn't trying to delude themselves.

I didn't say VRAM = System ram, I said performance will tank if you need more than you have of either one and bandwidth does not make up for capacity. If you think this is a false statement then you need to do some more research.

The logic fail here is not understanding that adding memory is the easiest way to get out of writing memory efficient code.

Stop being lame and asking that everything be spelled out; I would think that someone with a nice signature PC knows a little bit more about the history of computing...

You are stuck in the mindset that every generation *needs* more memory.

Well, maybe the game companies are just as guilty as the video card companies? And have been lazy about developing good code and doing more with less?

Maybe, the behind the scenes software is getting better and 4GB is physically plenty to do what is needed to do for non-VR applications? (For the next few years, until 6GB is *maybe* needed)

We all know you can't keep adding 2GB - 4GB every generation, just because.

I did, and responded. B-Riz post was completely ridiculous. "I don't know anything about AMD's compression or DX12 so that must make 4GB adequate" is essentially what he said. You referencing a post like that as if to say he made a good point makes this one equally ridiculous.

iiiankiii's post had more merit, but still doesn't address my concerns.

I thought B-Riz was referring to the compression algorithms used in Tonga (that IS a known), which is why I referenced his post.

I'm not here to convince you to buy a certain card. I was just pointing out that you ASSUMING that 4GB is insufficient for an unreleased card using a brand new memory tech from a company who had a previous card that addressed bandwidth issues using different thinking (than the standard slap more memory on), is a bit odd. You have yourself convinced that 4GB will definitely be insufficient and that's fine. I have a different opinion.

I didn't essentially say anything, ermahgerd, I want to rage so hard on your ignorance.

I stated there are too many unknowns to discount 4GB as being too little right now.

You don't have to add 2-4GB every generation, nor did I say every generation "needs" more memory, you're just making up more fairy tales. Going backwards though? Makes no sense to me.

I specifically said in a previous post from yesterday, 4GB is enough CURRENTLY but I do not want to find myself in the same situation with a 4GB card as I have found myself by buying a 2GB card 2 years ago.

Sure, there are plenty of unknowns, you go ahead and buy your next card assuming all the unknowns are going to work out in your favor. I'm going to buy one where I won't have to worry about it. If you're going to replace your card every year it's more then likely a non-issue. I plan on keeping my next card until I do my next complete build and depending on what's available then and what's "right around the corner" it may even get migrated to my next box for a short amount of time. I'm not going to buy my next card with hopes that DX12 will require less memory or that suddenly developers are all going to write "memory efficient code" I mean why would they? AMD has shown that their developer relations is horse poop and NVidia is moving beyond 4GB. Don't even get me started on your flawed compression theory. You want an example of ignorance, look no further than that.

I'm confused as to why anyone would buy this in stock form right now. (unless SLI, but why not wait for CLC?)

This card has good (really good) OC potential, and the better performers will not be using the stock cooler.

I went SLI, so the blowers work well for that.

I have a mid tower case and the single rear exhaust port is already used by my CPU CLC fan. I'd need to get a new case with two more ports in the back for the cards. Not worth the hassle for me.

Cost - already stretching it at $650.00. Small increases not worth it to me.

I only OC my video cards a small amount, no added voltage or anything, just so I feel like I OC'd them to get that little extra for free. I feel like if a stock GPU can't run a game well, adding a big OC won't make me happy either. When 2 cards can't cut it, its time to ditch them.

For instance, there is no pair of GTX 780ti's in the world, regardless of their insane uber voltage OC that would make them last any longer than a stock pair IMO. The gameplay experiences I've had with OC'd GPUs was not worth the effort for me, so I leave them alone for the most part. CPU's is a different story completely. If I had only a single GPU, I'd be all over OCing the crap out of it. Two is already overkill and lets the CPU stretch its legs fully.

Due to taxes on the EVGA website it actually ends up $100 cheaper to buy a 980 ti reference card on a site with no tax and the 980 Hybrid CLC separately.

Although I'm adamant about not buying another 28nm GPU, I have to hand it to NV: I actually thought about buying this for a split second. AMD has its work cut out for it with the 390X. It'll be interesting to see how that plays out. Price war?

I really hope the Fury is not 4GB of HBM. Anything less than 6GB is not acceptable considering console use 6GB of VRAM.

Hahaha...

6GB is minimum these days people! Don't buy anything that has less than the 6GB.

How fortunate for nv to make it stick with their today released card and meet the ultimate requirement of 6GB miniumum

Curious about the memory pool, given pixel fillrate dropoff.

It is an absolute masterful play from nVidia releasing this 980ti. I'm seeing so many people (from various sites) with 900 series cards upgrading to this. Seems sold out everywhere too, generating more buzz.

Was this a common occurance during Keplers hayday? People plopping down $330 for a 970, and $550 for a 980 at launch, buying into the 980ti at $650 8 months down the line.

I'm not sure, all I hear is console use 6GB of VRAM so since we are getting so many console port in the near future, it would make sense to have at least a 6GB Vram gpu.

Consoles have between 4.5 and 5.5GB of memory for games, while the rest is reserved for OS and whatever else functions there is outside of the game. This memory is shared between "vram" and system style memory.

So if a game uses 2½GB for gamedata then you may only have 2GB "vram".

That's what I thought.

But 3.5gb is enough! I mean its the full 4gb anyway when you need it.

I was just thinking about how hilarious it is that 3.5gb was fine a few months ago when the 970 issue came out but now anything less than 6gb is not only not future proof, but not good enough right now!

Either way, really impressive card from NVidia. I would have liked the pricing to be lower, but that's the name of the game right now.

Aren't the consoles shared memory?

Yes, it's shared, but the PS4 has a total of 8GB some people say 6GB is available for the game while others are saying it's 4.5-5GB. Either way you look at it, it's more than 4GB which is one reason why 4GB is a major point of contention, especially for a top end part.

No, you're missing a part of this. 4.5-5gb is what is leftover after the OS and hypervisor. The 5gb is what is remaining for the game assets and VRAM.

Or all those people that defended the GTX 960 for having 2GB of RAM vs the R9 280(x) at 3GB because 2GB was good enough then for console ports at 1080p (aka the same res as consoles).

What would be funny is if the 980 TI does the 970 trick. Then suddenly we will go from "Anything under 6GB isn't good enough" to "Oops, I meant 5.5GB!"

I think you'll find that most everyone is in agreement that it is good enough right now!

Solid card but waiting for asus dc ii 980 Ti or a custom fiji fury before taking the plunge.

I'm not missing it, I get it. VRAM is by far going to take the greater chunk and I expect a high end video card that costs more than an entire console to have more vram than a console. Not equal to, and certainly not less. I think that's the point you're missing.

I disagree. Here's a great breakdown for infamous: Second Son on how it is used: http://www.dualshockers.com/2014/04...am-cpu-and-gpu-compute-to-make-our-jaws-drop/

"Loaded Data" has to also included things like the physics, audio, and AI engines and their required information, etc. At most it's ~2-2.5gb of what would be considered "VRAM" on a PC.

I think people compare GPUs a bit wrong.

You have GTX 970 with 4GB and then you have GTX 980Ti with 6GB. Take 4K resolution for example. GTX 980Ti is playable with that, GTX 970 is not. Just look at this review and the 3-4 pages after this:
http://www.hardwarecanucks.com/foru...2-nvidia-gtx-980ti-performance-review-12.html
4K takes it toll on VRAM usage. Same can be said about lower res but with MSAA etc with all goodness enabled. GTX 980Ti is almost 50% faster in 4K than GTX 970.

So with a high end graphic card, with more and more console ports with less than desired optimization for PCs, 6GB is sorta the minimum today for a high end graphic card if you plan to have it working 100% all the time.
